Guiding Stars - The impact of nutrition rating systems on supermarket food sales

20.08.2014

Can nutrition rating systems be used in supermarkets to encourage healthier spending habits?

A new study by Cornell University researchers sought to answer that very question by tracking the purchasing records in a supermarket chain that uses the Guiding Stars System to rate the nutritional value of foods for sale.

The researchers, including Cornell Food and Brand Lab's David Just, PhD, and Brian Wansink PhD, author of Slim by Design (forthcoming), studied the sales records of over 150 Hannaford Supermarkets in the Northeastern United States between January 2005 and December 2007.

They collected data from over 60,000 Guiding Star rated food items. The Guiding Stars System brands items with zero, one, two or three star rating (with three stars being the most nutritious).

The amount of beneficial ingredients, such as vitamins and whole grains, are taken into account along with the amount of innutritious ingredients such as trans-fat or added sugars, both of which affect the nutritional rating of that item.

Researchers found that sales of less healthy foods – such as highly processed snack foods – fell by 8.31% when branded with a nutrition rating while the percentage of healthy food purchases rose by 1.39%.

The authors also noticed that the use of the Guiding Stars system led to an overall decline in supermarket sales. However, this is mainly due to the reduced amount of purchased "junk food."

According to lead author John Cawley, PhD, the decline in the sales of the less healthy foods was "perhaps the leading catalyst for the trend toward more nutritious food purchases." Previous studies may have not noticed this trend because they focused only on sales of foods with higher nutrition ratings.

Researchers concluded that nutrition rating systems, such as the Guiding Star system, may be worthwhile as they seem to lead consumers to purchase less "junk food" in favor of healthier options.

Im Focus: Basel Physicists Develop Efficient Method of Signal Transmission from Nanocomponents

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.

Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

Im Focus: Into the ice – RV Polarstern opens the arctic season by setting course for Spitsbergen

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.

RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...

Im Focus: Gel filled with nanosponges cleans up MRSA infections

Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.

To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
